The X-ray structure of S. aureus EI (SaEI) has been recently solved but structures of other bacterias have been reported before, for instance E. coli EI structure (EcEI). Although SaEI and EcEI X-ray structures are nearly the same, some differences have been observed. | The X-ray structure of S. aureus EI (SaEI) has been recently solved but structures of other bacterias have been reported before, for instance E. coli EI structure (EcEI).

These two X-ray structures could actually be two possible conformations of the Enzyme I, corresponding to two steps of the phosphotransfer from PEP to HPr. EcEI structure correspond to the conformation II and SaEI structure correspond to the conformation I. | These two X-ray structures could actually be two possible conformations of the Enzyme I, corresponding to two steps of the phosphotransfer from PEP to HPr.
